mirrors. >> tonight, obama stands alone -- his turn to defend his record. >> for more on what is at stake from that speech, i am joined now by mark. thank you for joining me. we were both down in tampa last week. one thing that struck me is that the mood is different up here. >> yes, i think it is. it is interesting. they tried to achieve different things from the platform. in tampa, there were quite excited. they thought they were on the verge of victory, but they did not want anything too wild, too crazy. a lot of people think they might not win. they are worried about their own state, where about how it goes, so the idea from the platform would be to ram them up, get the really exciting speakers to excite the crowd, to make them feel pumped up, make them want to go home and think, "yes, we can win this." >> what the candidates have to do in these critical speeches is also different, isn't it? >> yes, it is.
